eSDK.py: unset BBPATH and BUILDDIR to avoid eSDK failure
When executing eSDK test case, the following error appears.
WARNING: attempting to use the extensible SDK in an environment
set up to run bitbake - this may lead to unexpected
results. Please source this script in a new shell session
instead.
FileExistsError: [Errno 17] File exists: '/.../tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/selftest-esdk-fcuyzsqu/tmp/sysroots/x86_64/bin/pigz' -> '/.../tmp/hosttools/pigz'
So unset these two vars to avoid messing things up.
